Description

Because some special materials have the tendency to adhere on the screen surface, or become wedge, due to their humidity,plasticity or shape. This was reduces the production capacity of the screen and increases the downtime of the machine considerably . To solve this problem we use this self-cleaning screens with crimped or straight wires, which vibrate independently from one another, being excited by the vibration of the machine and also by the weight of the material to be screened. This is a noticeable increase in production and a longer using life of the meshes. These meshes also offer a high percentage of screening surface, which makes them highly recommendable for improving the production capacity.

Besides, Polyurethane cross straps of the self-cleaning meshes was greater wear resistance than metal straps and increase the screen's wear life. The crippled wires obtain a precise and effective screening. The wires vibrate independently from another one, avoiding the material build-up, pegging and blinding.

Characteristic

• It is particularly effective for screening crushed stone, sand and gravel, and materials with high water content, helping materials to stratification more quickly.

• Compared to standard woven square mesh, the screening efficiency is improved by at least 30%.

• Compared to standard woven wire screens with the same wire diameter, it has a larger effective wear area.

• Effectively reduce or solve the problems of pegging or blinding.

Harp Screen or Piano Wire       

• It has straight parallel wires, having the largest screening area with low precision. It is mainly used in end tension mobile screens to classify sands, gravel, and other dry materials.

• Maximum open area. Reduce fines for desanding andremoving fines.

• Lasts longer than traditional harp/piano wire, while keeping material in spec.

• Ideal for compost and topsoil.

Opening sizes: 0.5mm~50.8mm

Wire diameter: 0.6mm~8mm
